A view from above: The first explosion – Aaron Tang says he witnessed the first of the Boston Marathon bombings through a window from his office, about half a block from the finish line. "(There was a) big blast of fire, and smoke, but it all vanished so fast and (there's) not much left to see minus lots of shattered glass," he wrote on Flickr. The following images are what he saw on April 15, 2013. See all photography related to the Boston bombings.
